Answer:
nucleus
Explanation:
The majority of an atoms' mass comes from the protons and neutrons that make up its nucleus. Electrons are the least massive of an atom's constituent particles, with a mass of 9.11 x 10-31 kg and a size too small to be measured by current techniques.
Mixtures are made up of 2 or more pure substances. pure substance is just its self and a mixture is multiple substances.
Answer:
unsaturated solution
Explanation:
Given: Epsom salts have a solubility 26.2 grams.
By definition,Solubility is the maximum amount of solute that can be dissolved in 100 g of water.
A solution is called saturated solution when the concentration of solute becomes equal to its solubility.
If the concentration of solute is less than solubility it is called unsaturated solution.
In this case: solubility is 26.2 grams.
If we dissolve 26 grams of Epsom salt in 100 g of water , concentration of solute is less than the solubility(26.2 g in 100 g of water) , hence it is an unsaturated solution.
